Drift Definition Drift (drifting) is a racing term that refers to the series of operations that cause the front end of the car to point at a greater angle with the direction of the actual movement of the car body and allow the car body to slide sideways.

The conditional drift caused by the drift creates conditions that are ascribed to the fact that the rear wheel loses most (or all) of the grip, while the front wheel maintains grip (it can only lose a small part at most, and it is best to gain additional grip); At this time, as long as the front wheel has a certain lateral force, the car flicks and drifts.

There are 1 ways to generate drift. Pull the handbrake in the straight direction to play direction 2. Pull the handbrake in the turn 3 . After hitting the brakes in the straight road, you will play 4 in the direction. Turn on the brakes 5 in the turn. The rear-wheel drive with sufficient power (or the four-wheel drive ratio of the rear-wheel drive power distribution tends to drive the rear-wheel drive) slams the throttle and hits the direction when the speed is not very high.

Among them, 3,4 is the use of weight transfer (the weight of the rear wheel is transferred to the front wheel), which is the method of at least hurting the car. 1,2 is used only for four-wheel drive vehicles for front-drive and rally racing, and it is exempt unless you are not afraid of breaking the car. Note that 1 and 2, 3, and 4 are separated because the car's motion path will be very different. Important note: Drift cornering is the same as passing corners. There are speed limits, and the speed limit for drift cornering can only be a little higher than normal corners. The speed limit for drifting on hard ground is lower than usual.

As for the ultimate can not flick, with the friction coefficient between the tire and the road, the speed of the car, braking force, throttle size, the size of the front wheel angle, weight distribution, wheelbase, suspension soft and hard and many other factors. For example, it is easy to fling the car on rainy days and snowy roads. It is more difficult to fling the tail. The higher the speed, the easier it is to flick the tail (so the first safety driving is not to drive fast cars); (The teacher who taught me to drive told me not to drive the steering wheel too fast.) The smaller the wheelbase and the higher the vehicle body, the more weight transfer, the easier it is to flick (it is also easy to overturn!); the anti-rotation of the front suspension system The weaker the effect, the easier it is to flick.

If the control in the flick is drifting with the handbrake, then the handbrake should be released after the car has rotated to the desired angle.

The midway task of drift is to adjust the body posture. Because of the unevenness of the road surface, the degree of bending of the route, the cornering characteristics of the car and other factors will often change. Therefore, drivers often need to control the steering wheel, throttle, brakes, and even clutch (not recommended) to allow the car to follow the driver's desired route.

First of all, to explain the principle: To make the wheel slide a long distance, we should minimize the friction between the wheel and the ground; to make the wheel less slip, we should try to increase the friction. The method of reducing friction has been described above. One is to make the wheels turn too fast or too slow, and the other is to reduce the positive pressure between the wheels and the ground; the method of increasing friction is the opposite.

Among them, the way to make the wheels rotate too slowly is to step on the foot brake or pull the handbrake (re-emphasize: the foot brake is applied to the four wheels, and the handbrake acts on the rear wheels. Whether or not the handbrake acts on other wheels The cars I know that have hand brakes are all what I said.

Stepping on foot brakes: All four wheels will slow down. Ultimately, the front wheels lose more friction or the rear wheels lose more friction.

Handbrake: The front wheel will not lose friction and the rear wheel will lose a lot of friction, so it is prone to oversteer. Because the foot brake and the hand brake have the effect of deceleration, the car will soon stop sliding.

The real drift and if you want the wheels to skid over long distances, the only way to make the wheels spin at high speed is to have a car with enough LSD power to do so. Why LSD? Because the body drifts when the car drifts, the pressure of the outer wheel on the ground is high, and the pressure on the inner wheel is small. Vehicles without an LSD will experience a idling drive of the inner drive wheel and a slow turn of the outer drive wheel. The friction between the slow-turning wheel and the ground is large, and the side-slip of the car will stop quickly.

The car is divided into predecessor, rear drive, and four-wheel drive. It is impossible to idling at high speed without the driving force of the wheel. Then the front wheel of the front-wheel cannot do long-distance skidding. If the driving wheel (ie the front wheel) is idling at high speed and the side slip is more than the rear wheel, the drift angle will be reduced, so the front-wheel-drive cannot do long-distance drift. . Four-wheel drive cars are obviously possible. After driving? The front wheel of the rear drive has no driving force, but the front wheel can swing to an angle in the direction of the body's sliding, so the rear drive can also drift long distances.

The slippage distance is related to the speed before the start of the side slip. It usually slips and slows down, and finally it stops. However, if the venue permits and the control is good, it can theoretically make an infinitely long side slip. Because the slippery wheels still have a certain amount of acceleration, the skidding tires are also subject to resistance from the ground. When these two effects are balanced, the speed of the car will not be reduced. For example, Doughnut is one of the infinitely long drifts. Of course, it is also possible to make an infinitely long drift with a large turning radius.
